Can't suppress WHITESPACE warnings

[nadav-kooply]

I've tried adding an empty .editorconfig file in order to slowly add rules to an existing project.
When testing it with --severity error --verify-no-changes I get WHITESPACE errors for lines with trailing whitespace.
When I try setting trim_trailing_whitespace to false or unset I still get those errors.
I've tried disabling all sorts of dotnet_diagnostic codes like:

dotnet_diagnostic.IDE0055.severity = none
dotnet_diagnostic.SA1028.severity = none
dotnet_diagnostic.CA1062.severity = none
dotnet_diagnostic.CA1801.severity = none
dotnet_diagnostic.CA1822.severity = none
dotnet_diagnostic.SA1000.severity = none
dotnet_diagnostic.SA1001.severity = none
dotnet_diagnostic.SA1005.severity = none
dotnet_diagnostic.SA1025.severity = none

But nothing seems to work.
How can I disable this rule?

dotnet-format uses the Roslyn formatter to format whitespace and the Roslyn formatter always trims unnecessary whitespace from the ends of lines. There is no setting to control this behavior.

Okay.. that's kinda strange that it can't be turned off. Are there other similar settings that are hard-coded and can't be disabled?
